Title: Improvements in or relating to logical circuits
IPC: H03K3/037
Filed: 1959-09-28
Abstract: 928,090. Diode gating circuits; transistor bi-stable circuits. PHILIPS ELECTRICAL INDUSTRIES Ltd. (Philips' Gloeilampenfabrieken N.V.). Sept. 28, 1959, No. 32882/59. Class 40 (6). [Also in Group XIX] A diode gating circuit which delivers an output pulse whose amplitude exceeds a predetermined value at terminal 9 when a predetermined combination of steady input potentials are applied at input terminals 2-7 and a pulse of predetermined magnitude and sign is applied at terminal 8 comprises a first set of input terminals 2, 3, 4 connected through respective similarly poled diodes to one electrode of a capacitor 10 and a second set of input terminals 5-8 connected through respective diodes poled in the same direction as those connected to terminals 2-4 to the other electrode of the capacitor, each electrode of the capacitor being connected to a point of fixed potential through respective resistors 18, 19 and the output terminal 9 being connected to one side of the capacitor through a diode 20 which as regards its connection to capacitor 10 is poled oppositely to those connected to the input terminals. In the circuit shown in Fig. 1 each of the input terminals may assume either of two potentials, i.e. earth potential and a negative potential equal to that to which the resistors 18 and 19 are connected, the potentials at the terminals 2 to 7 being constant while that at terminal 8 being capable of rapid transitions between its two possible values. When one or more of the first set of inputs 2-4 is at earth potential the corresponding electrode of capacitor 10 is at earth potential. Similarly if all of the second set of inputs 5-8 are at the negative potential the corresponding electrode of capacitor 10 will. be at that potential. Thus under these conditions when the potential at terminal 8 executes a rapid positive change to earth potential, the potential of the lower electrode of the capacitor will change likewise and its upper electrode will go positive to earth so delivering a positive pulse output at terminal 9. As shown in Fig. 2 illustrating the application of the circuit to a binary counter or frequency-halving circuit, circuit 30 is a conventional reciprocally-coupled bi-stable pair of transistors which can be triggered from one state to the other by pulses 78 applied through a diode gating circuit 60 in accordance with the invention. In this circuit terminals 62, 64 constitute one set of input terminals and terminals 63, 65 the other set. Assuming that transistor 31 is conducting and transistor 32 is cut off, in the negative-going intervals between the switching pulses 78, one of inputs 62, 64 is at earth potential (viz. input 62) while both inputs 63, 65 are negative. Hence when the next switching pulse 78 arrives a positive pulse is delivered to output terminal 66 and is applied to transistor 31 to change the state of the circuit 30. Similarly the next switching pulse causes an output to appear at terminal 67 to switch the circuit 30 back again.

Abstract: 1392745 Detecting flaws magnetically ALLMANNA SVENSKA ELEKTRISKA A B 14 July 1972 [15 July 1971] 32996/72 Heading G1N Flaws in a metallic object 1 are detected by arranging a current carrying conductor 5 substantially parallel to the surface of the object 1 so that it generates a magnetic field in the object and detecting disturbances in the magnetic field by a probe 3 which moves over the surface of the object close to conductor 5. For testing steel billets, Fig.3 (not shown) the conductor 5 is curved so that it follows two adjacent sides of the billet and acts as a guide rail for the probe 3 which moves to and fro therealong. Alternatively the conductor 5 may be one side of a rectangular coil the axis of which is parallel to the surface of object 1, the magnetic fields due to the remaining three sides of the coil being negligible in the object. The movement of the coil and probe may in this case be linear or rotary to scan conductor 5 over the surface. The probe may include coils or Hall elements and more than one probe may be used pairs of which are differentially connected.

Abstract: 956,101. Frequency modulation; pulse modulation circuits. BENDIX CORPORATION. Aug. 30, 1962 [Sept. 29, 1961], No. 33366/62. Drawings to Specification. Headings H3R and H4L. A multivibrator is frequency modulated by a balanced amplitude modulated and amplified A.C. signal derived from a chopper having the multivibrator output as switching frequency for a D.C. modulation signal, so that the multivibrator itself acts as a synchronous demodulator producing a D.C. control voltage at its input controlling its frequency. The modulated pulse frequency is then applied through a bandpass filter to produce a frequency-modulated sine wave as output. The amplified A.C. may be applied in push-pull to the bases of a pair of transistors cross-coupled by R.-C. networks to form a multivibrator, the collector and base D.C. voltages being derived from potentiometers connected to a Zener diode stabilized supply voltage, to vary respectively the sensitivity and mean frequency. The multivibrator pulsed output is applied through a pulse shaping network to the chopper. This comprises a pair of transistors with the D.C. modulation applied between the collectors, and the switching pulses from the multivibrator in push-pull between the collectors and bases by a phasesplitting transformer, the two outputs derived from the emitter circuits being then differentially combined by an output transformer, to give a balanced modulator output, which is then amplified by a transistor amplifier. Specification 938,946 is referred to.
